OPTIONAL WOOD FRAME FLOOR LEVELING OPTIONS
There are multiple ways to level your floor frame. Our recommended leveling method is shown below.
Leveling materials are not included in this kit.
PREFERRED METHOD - 4x4 TREATED RUNNERS (Typical for 10' x 12' Kit)
• 3" Screw angled into 4x4.
• (2) at each point frame and 4x4 touch.
• Level under 4x4 runners only.
• Locate leveling material 12" from ends of runners and no more than 48" apart.
• Asphalt shingles should be used between 4x4 runners and blocks or treated lumber. Never use
shingles in direct contact with ground.
• For best results and aiding in water drainage use gravel under each concrete block.
